IMPROVEMENT IN M XitG ARD GRINDING APPARATUS FOR |NK,&c.

-To all whom it may concern:

Be it known that I, JOSEPH MARTIN, of the city, county, and State of NewYork, have invented a new and useful Improvement in Ink and Paint Mixerand Grinder, of which the following is a specification:

Figure l is a detail vertical section of my improved machine. Fig. 2 isa top view of the same, partly in section, through the line 00 as,Fig. 1. Fig. 3 is adetail horizontal section of the mixer taken throughthe liney y, Fig. 1.

My invention has for its object to furnish an improved machine formixing and grinding printers ink, paint, &c., which shall be simple inconstruction and effective in operation, mixing and grinding the ink andpaint thoroughly and with much greater rapidity than is possible whenthe mixing and grinding are done with the ordinary appliances. Theinvention consists in the stationary vessel, revolving core, andinduction-tube, constructed and arranged to operate in connection witheach other, as hereinafterfully described; in the combination of themixin g-vessel, the valve, the cross-bar or scraper, and post with theinduction-tube, revolving core, and stationary vessel; in thecombination of the weighted lever with the induction-tube, revolvingcore, and stationary vessel; and in the arrangement of thedischarge-spout and scraper, in connection with the notched upper edgeof the stationary vessel and with the revolving core, as hereinafterfully described.

Ais a stand to whichis secured or upon which is formed a vessel, B, theinterior of which is made in the form of an inverted truncated cone, asshown in Fig. 1, and which forms the outer part of the grinder. C is theinner part of the grinder, which is also made in the form of an invertedtruncated cone, and which fits into the interior of the vessel B. Thecore 0 should not extend quite down to the bottom of the vessel B, spacebeing left between the bottoms of said parts for the ink and paint topass from the center of said part 0 to its circumference. Upon the topof the core 0 is formed or to it is rigidly attached a bevel-gear wheel,D, into the teeth of which mesh the teeth of the bevel-gear wheel Eattached to the inner end of the'shaft F. The shaft F revolves inbearings in brackets attached to the vessel B, or to some other suitablesupport. The shaftF may have pulleys G attached to it to enable it to bedriven by steam, or it may have a crank, H, attached to its outer end toenable it to be operated by hand. I is a tube, the lower end of which isconnected with the upper end of the cone or part 0 at the upper end of aperforation that extends down through the center of the said part 0. Tothe upper end of the tube I is attached a vessel, J, in which the inkand paints are mixed, and which I prefer to make in the shape of atruncated cone to prevent said ink and paint from spattering out. K is arigid stationary post of a smaller diameter than the interior of thetube I and the hole through the core 0, and which may be groovedspirally, if desired. The lower end of the post K is secured to thebottom of the vessel B, and its upper end projects into the mixer J. Lis a valve, through which the post K passes, and which is connected byarms M with a nut, N, screwed upon the upper end of the post K, so thatby turning the said nut downward the valve L will be lowered to itsseat, closing the upper end of the tube I, and retaining the ink orpaint in the vessel J until it has been thoroughly mixed. By turning thenut N upward the valve L will be raised, allowing the ink or paint toflow down through the tube I to the grinder. To the upper part of thepost K is rigidly attached a cross-bar or scraper, O, in such a positionas to be close to the bottom of the vessel J, so that the ink or paintmay be thoroughly mixed before it is allowed to flow down into thegrinder. The valve L moves up and down upon the post K in a recess inthe lower side of the middle part of the bar or scraper 0. When thevalve L is raised the bar 0 acts as a scraper to force or guide thepaint or ink into the tube L. As the ink or paint passes down throughthe tube I, and the perforations of the core (3 into the space betweenthe bottom of the said core 0 and the bottom of the vessel B, it isforced by v its own gravity and the centrifugal force engendered by therevolution of the core,

to pass up between the outer surface of.

the revolving core 0 and the inner surface of the stationary vessel B,being thoroughly rubbed and ground during its passage. In the upper edgeof the vessel B is formed a notch, in which is secured a spout, P,through which the ground ink or paint is discharged into a receiver, Q.To the vessel B is attached a scraper, R, which is so formed as to enterthe notch of the vessel B, and bear against the upper part of therevolving core 0 to scrape off the ink and cause it to flow'into thespout P and thence into= the receiver Q. S is a lever, which is slottedto receive the tube I, and is pivoted to a bracket attached to thestationary vessel B or other suitable support. The lever S rests uponone or more ring-washers, T, placed upon the tube I, and which rest uponthe top of the core 0. The other or free end of the lever S has asliding weight, U, placed upon it, so that by adjusting the said weightU the core 0 may be forced down with any desired force to grind or rubthe ink or paint more or less, as may be desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The stationary vessel B, revolving perforated core(J, and induction-tube I, constructed and arranged to operate inconnection with each other, substantially as shown herein and described.

2. The combination of the vessel J, valve L M N, cross-bar O, and post Kwith the induction-tube I, revolving core 0, and vessel B, substantiallyas herein shown and described.

3. The combination of the weighted lever S U with the tube I, revolvingcore 0, and stationary vessel B, substantially as herein shown anddescribed.

4. The arrangement of the discharge-spout P and scraperR in connectionwith the notched upper edge of the vessel B and the revolving core 0,substantially as herein shown and described, and for the purpose setforth.

JOSEPH MARTIN.
